从旧答案中使用我的旧演示的主要问题在于代码行
this.processing = true;
jqGrid 现在在大多数回调函数的调用中初始化this为表 ( ) 的 DOM 元素。$("#list")[0]所以上面的行必须固定为
options.processing = true;
还有其他一些小的变化也应该实施。最重要的是调用对$.unformat.date格式化程序使用的所有字段进行解码"date"。
新的演示使用了 jqGrid 4.4.1，你可以在这里找到。
您将在下面找到完整的代码

PS我没有用TreeGrid测试代码，但我希望它也能工作。可能还需要$.unformat.date使用“日期”格式化程序对列进行相同的调用。
